A Microsoft Azure Case Study
Exclaimer, the world’s largest provider of email signature management used by millions of organizations, faced a major shift as customers migrated from on‑premises servers to the cloud. To remain competitive and integrate with Office 365, the company needed to rethink its product architecture, address customer concerns about email security and data residency, and build a cloud-native solution that could scale globally.
Exclaimer built Exclaimer Cloud – Signatures for Office 365 on Microsoft Azure as a relay service so messages never leave the Microsoft Cloud, leveraging Azure’s scalability, automatic failover and load balancing. The solution now processes about 17 million emails a day, serves over one million cloud users, spans 14 Azure datacenters for data residency, and has transformed Exclaimer from an on‑premises vendor into a cloud‑first provider during its fastest period of growth.
